When you are doing what you do...whether it be running, biking, weight lifting, practicing yoga, crossfitting...or whatever...Pay Attention. Concentrate. Notice everything.
Learn to feel.
Know your pace. Know your effort level. Know your heart rate. Know your breath. Know your lactate levels. Know your energy levels. Know your hydration levels. Know if you need protein. Know if you need carbohydrates. Know if you are too acidic. Know how you feel. At first you might need a watch or Garmin or heart monitor or tests or other bits of biofeedback. But work towards knowing these things without any assistance.
The only way to develop these skills is to pay attention.
If you learn to tune in, you'll learn what works and what doesn't work...for you. You're training will improve because it will be based on how you feel and your knowledge of what works and what doesn't work. It will be based on first-hand experience...rather than something you read...or what some bozo (like me) on the internet told you.
If you are aware, you learn through your experiences. If you are not aware..they just pass you by.
Let's all work on improving at this. More to come...

answers. they want you to believe theirs.”
